Unity Behavior Tree Library – Fluid

While there are tons of unity behavior tree libraries on the Asset Store. I haven’t found one that meets all my game dev needs. There is the amazing Fluent Behavior Tree library. But for me it’s missing features and the project isn’t currently in development. What I’ve been craving is an open source Unity behavior tree library that’s easily extendible.

I’m proud to announce Fluid Behavior Tree. An open source behavior tree system that’s easily extendable without forking the code. This means it’s updatable and quite resilient to breaking changes on upgrade.

Why is this better than other Unity behavior tree libraries?

Most behavior trees for Unity are paid products. There’s nothing wrong with premium paid projects (and devs should be paid for their time). But it can be difficult to share code for proprietary software. Paid projects also run the risk of being deprecated or having difficulty getting enough critical mass to start a continued community.
